Re 'guns' - so what if he shoots the gun at home before, he can still use it again, right?
My H can still do it if you leave him half an hour in between times. I remember one birthday I had in happier years, we ML 3 times in one night!
So is de-loading really gonna help? Or is this a man subject I know nothing about?
Tingley thing is normal sexual excitement. I get that holding my H's hand, and did in the M too, just from hand-holding. In fact, you can get it just thinking something nice. Perfectly normal response, don't feel guilty about it. The women would probably be flattered if they knew.
